The Spanish football league system is divided into two main groups: the Primera Division (also known as La Liga) and Segunda División (or Tercera División). These divisions are based on the number of teams in each group, with the highest division being the top tier.

In the Primera Division, there are ten clubs, including Real Madrid, FC Barcelona, Valencia CF, Atlético de Madrid, Real Sociedad, Sevilla FC, Atletico Madrid, Espanyol, Villarreal CF, and Granada CF. The club that finishes at the top of the table receives the title of "La Mayor". This year's season will be the first since the COVID-19 pandemic, and many clubs have had to adjust their schedules due to the restrictions placed by the government.

On the other hand, in the Segunda División, there are six clubs, including Real Betis, CD Leganés, Real Sociedad CF, Celta Vigo, Real Madrid B, and Athletic Bilbao. The club that finishes at the bottom of the table receives the title of "La Menos".

Both leagues feature some of the best players in the world, and it is often said that the quality of play in the Primera Division is better than in the Segunda División. However, both leagues also have their share of talented players who can make a big impact on the field.

For example, Real Madrid has been one of the most successful teams in the Primera Division in recent years, winning three consecutive titles in the league. Meanwhile, FC Barcelona has won four consecutive La Liga titles, while Valencia CF has won three consecutive Segunda División titles.

However, the competition in the Primera Division is intense, and many of these teams have struggled to compete for titles this season. Despite the challenges faced by these clubs, they still have great potential to challenge for titles in the future.
